To improve the management of irrigation district is a key to develop water-saving agriculture. Based on the basic principles of water-saving irrigation, and using the method of Modified Penman Monteith and water balance equation, The system of irrigation management and decision support based on WEBGIS was developed,which is according to the soil moisture, crop growth status, meteorology change ...

water user associations (wuas) are one of the water market development models and a way to transfer the irrigation management from government sector to water users which have been increasingly taken into account over the recent years. in iran accordingly, a number of wuas has been developed in downstream dam irrigation and drainage networks on pilot scale. the major goal of wuas is to improve w...

Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...

BACKGROUND The established treatment for bacterial arthritis of the knee joint is arthroscopic surgery with irrigation and debridement. The aim of this article is to summarize the relevant data in treating bacterial arthritis of the knee joint, and based on these findings to present a novel irrigation suction system, tested in a cadaver study, as an additional tool in the postoperative treatmen...

Recent drought and population growth are planting unprecedented demand for the use of available limited water resources. Irrigated agriculture is one of the major consumers of fresh water. Huge amount of water in irrigated agriculture is wasted due to poor water management practices. To improve water management in irrigated areas, models for estimation of future water requirements are needed. D...

This paper argues that the 'optimization along trajectories' formulation of the distal learning approach [1] doesn't work on non-minimum phase dynamical plants [2] and the 'local optimization' one doesn't work on plants with variable or badlyestimated time-delay. It then proposes a modification of the procedure and illustrates improvements on the control of a simulated irrigation canal. This pa...
